vApplication filed October 14, 1902. Serial No. 127,249. (No model.)

T0 @Z5 whom, t may concern.

Be it known that I, CHAUNCEY BERTRAM CORL, a citizen of the United States, residing at Riverside, in the county of Riverside andl State of California, have invented a new andY usefulHorse-Controlling Device, of whichthe' following is a specification.

This invention relates to means for controlling horses, and is designed to providean improved device of this character which is operated from one of the wheels of theV vehicle and is arranged to be thrown into and out of operation by the driver. It is furthermore designed to have the device exert a strain upon the animals head should he attempt to move forwardly and to automatically relieve the strain when the vehicle is backed.

Another object is to lock the device in engagement with one of the vehicle-wheels when in operation, so as to prevent accidental disengagement of the device from the driving element.

With these and other objects in view lthe present invention consists in theeombination and arrangement of parts, as will be hereinafter more fully described, shown in the acoompanyingdrawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within Jthe scope of the claims without departing from the spirit orsacriioing any of the advantages of the invention.

In the drawings, Figure lis a rear elevation of the present device applied to the axle of a vehicle, a portion of the casing being removed to show the parts housed therein. Fig. 2 is a sectional view taken on the line 2.2 of Fig. l. Fig. 3 is a detail sectional view taken on the line 3 3 of Fig. l. Figll is a cross-sectional view of Fig. 3 on the line 1l 4.

Like characters of reference designate corresponding parts in all the iigures of the draw ings. A

For adequately illustrating the application and operation of the present device there has been shown in the accompanying drawings a portion of an ordinary axle l and one of the wheels 2 thereof, the inner end of the hub of the wheel being provided with a gear 3 for operating the present device, as will hereinafter appear.

4which is connected to the upper end of the casing, with the other member connected to a clip 8,embracing the axle, there being suitablemeans, as will be hereinafter described, for moving the casing vertically upon its hingedsupport to throw the pinion 6 into and out of mesh with the gear 3. Upon the middle portion of the shaft, which is within the box creasing, is a loosely-rotatable drum 9, which is frictionally embraced by the strap l0, that enters the upper front portion of the box or casing through an opening 1l, thence I passes across the upper rear vand lower sides of the drumLand thence outwardly and downwardly through an opening l2 in the lower front portion of the casing. The up per forward portion of the strap is split or divided into longitudinal members 10*,whicl1 runforwardly and are connected to the opposite ends of the bridlebit, and as this arrangement is perfectly obvious itv has not been deemed necessary to illustrate the strap members connected to the bit. As best indicated in Fig. 3,'it will be seen that the strap is held snugly inv friyct-ional lengagement with the periphery of the drum by means of an antifriction-roller 13, which bears against the lower portion of the strap and is carried by the upwardlyfinclined free end of a spring-arm 14:, secured to the bottom of the casing, whereby the strap is prevented from slipping upon the drum. A collar l5 is keyed upon the shaft at the inner side of the drum and is designed to form an abutment to limit lateral movement of the drum and toraid in interlocking the latter with the shaft. At

the outer side ofthe drum the shaft is provided with a worm or screw-threadid, and upon this screw-threaded part of thel shaft is a peripherally-toothed ratchet-disk 17, which is adapted to be fed toward and away from the drum by the rotation of the shaft when the pinion 6 is in mesh with the gear 3.

roo

The ratchet-disk is held against rotation in the direction ofthe arrow shown in Fig. 3`

will be noted that when the shaft is turnedy in the direction of the arrow shown in Fig. 3 the disk will be held stationary by the dog and therefore the worm or screw-threaded part 16 of the shaft will feed the disk laterally away from the drum, and upon a reverse rotation of the shaft the disk will be fed in the opposite direction into frctional engagement with the drum, as the pressure of the dog 18 is suflicieut to prevent rotation of the disk until the latter has engaged the drum and forced the same into engagement with the abutment 15, when all three of these elements will be interlocked and, through the medium of the abutment 15, will also be interlocked with the shaft for simultaneous rotation therewith in the direction opposite to that indicated by the arrow in Fig. 3, whereby the strap members 10a will be drawn rearwardly and a strong tension placed upon the head of the animal, so as to check any furtherforward movement. When the vehicle vis backed, the ratchet-disk will be fed away from the drum, and as the latter is then loose upon the shaft the animals head is released.

For throwing the device into and out of operation that portion of the shaft 4 which is between the box or casing and the pinion 6 is journaled in the lower side of a horizontally disposed substantially U shaped bracket 19, the upper side of which lies across the under side of the axle and is secured thereto by clip 20. The bracket is elastic, so that its lower side may be moved vertically to bring the pinion 6 into engagement with the gear 3, the forward end portion of the lower side of the bracket forming a projection 21 to work in the slotted or bifurcated part of the pendent guide-arm 22,which hangs from the forward end of the upper side of the bracket. To raise and lower the lower side of the bracket,there is an upstanding lever 23, the lower end of which is bifurcated, so as to straddle the upper side of the bracket in rear of the axle, and is fulcrumed thereon by means of a pivot-pin 24, passed through the side of the bracket and the bifurcation. A pair of links 25 embrace the lever and the bracket, with their lower ends pivotally connected to the lower side of the bracket, as at 26, and in front of thefulcrum of the lever, with the upper ends of the links pivoted to the lever at a point above the f ulcrum thereof, as indicated at 27. A strap or other flexible connection 28 is secured to the upper end of the lever and extends into the vehicle for convenient operation by the driver, so that by pulling upwardly upon the strap the lower side of the bracket 19 will be drawn upwardly and the pinion 6 ymeshed with the gear 3, whereby the device is thrown into operation to check the horse 4in the manner hereinbefore described. y

A very important feature of the present invention is best illustrated in Fig. 2, wherein it will be seen that by having the pivotal connection 26, between thelinks 25 and the lower side of the bracket 19, disposed in front of the fulcrum 24, with a portion of the clip 2O disposed in the forward path of the links, the strain upon the links tends to draw the lever forwardly; but as the links lie against the portion of the clip and cannot move forwardly the lever is automatically locked and accidental disengagement of the pinion 6 from the gear 3 is precluded. The pinion 6 is disengaged from the gear by throwing the lever 23 rearwardly, and this disengagement is quick and positive under theinliuence of the elastic lower side or member of the bracket v19.

From the foregoing description it is apparent that the device of the present invention is complete in itself, and therefore no change or alteration whatsoever is required in the running-gear of the vehicle in order that the device may be applied thereto, as the gear 3 may be readily fitted to the hub in any suitable manner without requiring any alteration therein, and the clips 8 and 20 are the ordinary U -shaped axle-clips, which embrace the axle in the usual manner.

It is preferred tomount the drum upon a frame or casing and to have the latter pivotally supported rather than to have one of the journals of the drum loosely supported, so as to permit lateral movement thereof, as the latter arrangement gives too much looseness to the journalsof the drum, while the former arrangement obviates such looseness and at the same" time permits of the required swing ing movement of the drum.
